UNITED STATES PATENT OFFICE.

O. C. EVANS, OF NEW YORK, N. Y.

LAMP.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, ORnRoD C. EVANS, of the city and county of New York and State of New York, have invented new and useful Improvements in Lamps for Burning Coal and other Oils, as Well as Non-Explosive Fluids, WVithout the Aid of a Chimney.

' munication between the gas chamber .and

the flame.

The upper end of the wick tube is perforated with holes or slotted openings for the purpose of allowing the gases and vapors which are liberated from the oil ,or fluid in the wick, by the heat communicated thereto, to freely pass into the gas chamber,and from thence out at the slits, or any other equivalent openings.

The object of this invention may be clearly perceived, from the many difliculties heretofore experienced in the burning of coal and other highly carbonized oils, free from smoke, without the aid of a chimney. But which, from this, my construction of lamp, is fully obviated,and not only this, but a larger flame with slightly diminished intensity of heat only is obtained, and this by converting a portion of the oil or fluid of the wick into gas or vapor, and then collecting and carrying it forward, in the man ner described, to feed the wick flame. Nonexplosive oils and fluids only can be used.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Reference being had to the accompanying drawings Figure 1, is a vertical sectional view showing the arrangement and construction of the various internal parts. Fig. 2, is a transverse view of the same.

Figs. 1 and 2: Letters A, A, represent a 31,160, dated January 22, 1861.

gas chamberand letters t, t, t, are tubes forming a part of the same.

Fig. 2: Letter .9, is a slit, running the whole length of the upper inner sides of the horns t, t, Fig. 1.and which should be sufficiently open. to admit vapor to pass, freely, through.

Holes or parallel slots are perforated in the upper end of the wick tube, and within the gas chamber, Fig. 1, letters B, and a a a up to any number required.

Guards, to prevent any vaporous fluid from running from the top of the wick tube,

next the flame, over and down the sides of the gas chamber, letters 0, C, C, Figs. 1 and 2, are placed around the wick tube, and soldered or otherwise fastened to the gas chamher.

A petticoat cone, letters D, D, Figs. 1 and 2, is placed between thegas chamber and the usual cone, which divides the air chamber into two chambers, instead of one.

From this the operation may be clearly A traced. The flame communicates to the surrounding parts, heat. From this heat vapors and gases are liberated, from the oil or fluid in the wick, before it reaches the flame, and which escapes through the holes or slots in the upper end of the wick tube, into the gas chamber and from thence it passes up through the slits in the same, to feed the wick flame, and from the position of these slits in the gas chamber it will be readily perceived how the flame of the wick is widened by the heated gases and vapors as they pass through, without the aid of a cone even. The guards, petticoat cone and cone graduate the current and amount of air to the different parts of the flame, at the bottom least, and where it leaves the outside cone, most. Hence care must be had in adjusting the height of the guards as well as the length, width and position of the petticoat cone ;-which should not extend below {Jody of the lamp up through the gas chain- I What I claim as my invention and desire to secure by Letters Patent of the United 5 States is,

1. The combination and arrangement of the gas-chamber A, constructed with horns t t, and slitted openings as described, With the openings of the wick tube a a a &c.

2. In combination with the gas chamber 10 and openings in the Wick tube, of the guards C G and petticoat cone D, the same being arranged in the manner and for the purposes set forth.
